This is the simplest and most flexible option. It is possible to run a DC power bus alongside the RS485 bus, however, this option requires careful consideration of the wire diameter. This method also increases the likelihood of EFT or surge voltages along the DC bus. 4.1.1.2 DC power wire diameter considerations Power connections are recommended to be a minimum 18 AWG, tin-coated, soft drawn copper per ASTM B8, Class B stranding, 300V rated. Insulation shall be EP (ethylene propylene) or EPCP (ethylene propylene chlorosulfonated polyethylene compound). If bussed power is being considered, the wire gauge must be selected to prevent excessive voltage drop between the DC power source and the reader that is electrically farthest from the source. The larger wire diameter required could force the use of a custom cable for DC power as the power bus wire cannot be the same gauge as the communications bus (RS485). Most standard RS485 bus installations use wire diameters of about 0.5mm or 24 AWG; this wire size may be too small to properly support DC power to all the readers if there are many readers a bus. 4.1.1.3 Functional Earth wiring Functional earth (FE) connection should always be installed between the reader’s FE terminal, FE post, and the FE connection in the low-voltage compartment. FE at the cable connection shunts transients at the cables, while case ground provides both RF shielding and safety against induced voltages on air interface cables.

Installation Manual Page 17 of 28 IRM-48 Reader 910.00371.0001 IMPORTANT There are two INDEPENDENT connections that shall be individually wired to the Protective Earth of the installation site such that there is an extremely low impedance between the enclosures; this is best achieved using the shortest possible ground cable. 4.2 COMMUNICATION CONNECTIONS The IntelliSAW readers are connected in a network using a standard, half-duplex RS485 bus. This is a 3-wire bus, differential signals for data +/- and a common signal return. The common signal is clamped to PE for safety and connects to the line driver through a high resistance to prevent ground loops. The figure below shows the various elements of a network in a switchgear substation. Figure 11: RS485 Data Communication Bus Topology 4.2.1.1 Recommended Cabling IntelliSAW recommends the use of shielded cable for the RS485 wiring, providing at least one twisted pair, one single line, and a drain wire, although typical cable has two twisted pair. The twisted pair provides DATA+/- signals to each reader while the single line would be for D-COM, providing a low-impedance return for each reader. 4.2.1.2 Bus cable shielding The drain wire associated with the RS485 bus shielding foil should be connected to the protective earth at the source end (the end of the line segment closest to the bus master) with the destination end left unconnected. This prevents ground loops and induced noise. Each

Installation Manual Page 18 of 28 IRM-48 Reader 910.00371.0001 segment of the bus should be shield-terminated to the protective earth in the cabinet from which it originates. 4.2.1.3 Bus resistive termination The RS485 bus needs to be terminated at each end with 120 Ω resistors when long stretches of cable are used. This ensures that the bus has the correct impedance. In general, RS485 adapters and bus masters provide the source impedance internally and should be located at one end of the bus. If the bus length is less than 2% of the maximum (20 meters at 9600 baud), the termination resistor may be omitted, as long as the bus master has termination and failsafe resistors. 4.2.1.4 Bus data rate (baud rate) considerations The RS485 bus data rate is dependent on the bus cable length and the number of readers on the bus. In industrial environments, slower data communication rates are generally more reliable; IntelliSAW recommends either 19200 baud or 9600 baud for the data rate. Bus length Bus cable length has an impact on the overall data rates which can be achieved. A conservative rule for RS485 uses the equation: (baud rate * cable length (m)) < 10 x 106. A 9600 baud network would require a bus less of (10 x 106 ÷ 9600), or 1042 meters (about 3400 feet). This is perfectly adequate for most substation installations. Number of Readers As the number of readers increase on the RS485 bus, the baud rate must be adjusted to accommodate the electrical characteristics of the communication protection circuits. The following table is a guide for number of readers versus system baud rate: Readers Baud Rate 1 115,200 1 – 8 38,400 1 – 16 19,200 1 – 32 9,600

Installation Manual Page 21 of 28 IRM-48 Reader 910.00371.0001 6 SYSTEM INTEGRATION The IRM-48 Reader has one RS485 slave communication connection. The Reader can be connected to a CAM-4 unit or an existing SCADA, DCS, or historian system. All IRM-48 readers are slave devices polled by either a Master CAM-4 unit or SCADA system. The following Modbus information is for Reader Firmware rev.1123 or higher. For legacy Modbus Register data, please contact IntellISAW support. 6.1 MODBUS COMMANDS The Reader treats holding and input registers identically; however HOLDING registers are the preferred approach. Modbus-RTU payloads always begin with the address and a function code (FC). The Reader supports the following Modbus function codes, as shown in the following table: Command FC Description 2 Function code required by CiTect MBF_READHOLDING 3 Fetch up to 81 of 256 defined registers MBF_READINPUT 4 Exactly duplicates the MBF_READHOLDING command with the same registers MBF_PRESETSINGLE 6 Set a single register – do not use in reserved registers MBF_DIAGNOSTICS 7 Sub-functions supported are 1, 4, 10-14 MBF_FETCH_CEC 11 Return 0x0000 if not busy, 0xFFFF if busy MBF_PRESETMULTIPLE 16 Set up to registers MBF_RESET_COMM 19 Reset reader processor if successful. MBF_RESET_COMM_ISR 7E

<7E> <55> resets reader XMS_XMESSAGE_FC 7F The remainder of the payload contains a native command. Modbus-RTU payloads obey the MODICON standard except for special function codes, 7E and 7F. For the 0x7F function code, the payload begins with address and 0x7F followed by an IntelliSAW native protocol command payload. The MBF_RESET_COMM_ISR command is a special sequence that reboots the processor from within the serial receive interrupt service routine, regardless of protocol, when it is detected from a serial line idle condition. The MBF_RESET_COMM_ISR command must be properly formatted and successfully parsed. This special sequence offers a means of resetting a reader that is otherwise externally unresponsive.
